Policywala Forums have thread rating system, where you can rate a thread to give your feedback on the importance of the particular thread.

There is a small menu at upper right of the post named ôRate Thread", which allows you to 'rate this thread' from a scale of 1-5.

Casting a vote for threads is entirely optional, but if you think that the thread is superb, you might rate it as a 5-Star thread, or if you think that it's unspeakably dismal, you might choose to rate the thread with a single star.

Once enough votes have been cast for the thread rating, you may see a set of stars appear with the title of the thread in the thread listings. These stars reflect the average vote cast, and would be indicative of the popularity of that thread amongst the forum community.
